We demonstrate continuous-frequency electric field measurements of high-intensity microwaves via optical spectroscopy in a small atomic vapor cell. The spectroscopic response of a room-temperature rubidium atomic vapor in a glass cell is investigated and employed for absolute measurements of K_a-band microwave electric fields from ∼200 V/m to >1 kV/m over a continuous frequency range of ± 1 GHz (15 established that in strong microwave fields frequency-specific spectral features allow for
